One of the pivotal challenges in this field is the designation of a consistent interpretation framework within which we can describe quantitatively the universal features of those systems. Here we analyze in a detailed manner the principal experimental data and compare them quantitatively with the approach based on a single-band model of strongly correlated electrons supplemented with strong antiferromagnetic (super)exchange interaction (the so-called t−J−U model). The model rationale is provided by estimating its microscopic parameters on the basis of the three-band approach for the Cu-O plane. We use our original full Gutzwiller wave-function solution by going beyond the renormalized mean-field theory (RMFT) in a systematic manner. Our approach reproduces very well the observed hole doping (δ) dependence of the kinetic-energy gain in the superconducting phase, one of the principal non-Bardeen-Cooper-Schrieffer features of the cuprates. The calculated Fermi velocity in the nodal direction is practically δ-independent and its universal value agrees very well with that determined experimentally. Also, a weak doping dependence of the Fermi wave vector leads to an almost constant value of the effective mass in a pure superconducting phase which is both observed in experiment and reproduced within our approach. An assessment of the currently used models (t−J, Hubbard) is carried out and the results of the canonical RMFT as a zeroth-order solution are provided for comparison to illustrate the necessity of the introduced higher-order contributions."}],"date_published":"2017-01-13T00:00:00Z","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","department":[{"_id":"MiLe"}],"doi":"10.1103/PhysRevB.95.024506","article_processing_charge":"No","author":[{"last_name":"Spałek","full_name":"Spałek, Jozef","first_name":"Jozef"},{"full_name":"Zegrodnik, Michał","first_name":"Michał","last_name":"Zegrodnik"},{"last_name":"Kaczmarczyk","full_name":"Kaczmarczyk, Jan","first_name":"Jan","orcid":"0000-0002-1629-3675","id":"46C405DE-F248-11E8-B48F-1D18A9856A87"}],"intvolume":"        95","oa":1,"oa_version":"Submitted Version","issue":"2","type":"journal_article","day":"13","isi":1,"scopus_import":"1","status":"public","volume":95,"_id":"1162","publication":"Physical Review B - Condensed Matter and Materials Physics","external_id":{"isi":["000391852800006"]}}
